我已经更改了我的应用程序，因此用户可以对整个应用程序有 2 种不同的样式。我已经更新了我创建的自定义选项卡，因此它们链接到一个样式，该样式反过来（取决于所选样式）链接到可绘制的 Selector xml（即显示选择或未选择的内容）。

运行它会给我以下错误

自定义背景代码

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:id="@+id/tabsLayout" 
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:orientation="vertical" 
    style="?custom_tab_background_selector">

    <TextView 
        android:id="@+id/customTabsText" 
        android:layout_width="wrap_content"
        android:layout_height="wrap_content" 
        style="?custom_tab_text_selector">
    </TextView>

</LinearLayout>

调用这个的方法

private static View createTabView(Context pContext, String pTabTitleText) {

        View view = LayoutInflater.from(pContext).inflate(R.layout.custom_tabs_background, null);

        TextView tv = (TextView) view.findViewById(R.id.customTabsText);

        tv.setText(pTabTitleText);

        return view;

    }

剩下的只是一个 xml 主题，它指向一个 Selector XML，后者又指向一些可绘制的 xml 文件。这是选择器 XML

<?xml version="1.0" encoding="utf-8"?>
<selector 
    xmlns:android="http://schemas.android.com/apk/res/android">
    <!--  Active tab -->
    <item 
        android:state_selected="true" 
        android:state_focused="false"
        android:state_pressed="false"
        android:drawable="@drawable/custom_tab_background_selected_black" />
    <!--  Inactive tab -->
    <item 
        android:state_selected="false" 
        android:state_focused="false"
        android:state_pressed="false" 
        android:drawable="@drawable/custom_tab_background_unselected_black" />
    <!--  Pressed tab -->
    <item 
        android:state_pressed="true" 
        android:drawable="@android:color/transparent" />
    <!--  Selected tab (using d-pad) -->
    <item 
        android:state_focused="true" 
        android:state_selected="true"
        android:state_pressed="false" 
        android:drawable="@android:color/transparent" />
</selector>

关于我为什么会收到此错误的任何想法都会很棒。谢谢你的时间

It appears I tracked it down.

the background of the tab I was using android:background=.... but was also using the same for the colour of the text and it should have been android:textColour=....

all works now. Sorry for the confusion
